Selena Gomez shows her support of BFF Taylor Swift by performing a choreographed dance with her girlfriend to I Knew You Were Trouble. Now THAT’S friendship! Plus, Selena definitely has some hot moves!

Selena gathered some of her friends for a little girls' night, which turned into a dance party for their friend Taylor! She tweeted a photo from the night, saying, “And then we danced til midnight” and “What I needed right about NOW :)” Hm, sounds like Selena needed a night away from the Biebs.
